説明
HistoryRetention プロパティを取得できるのは、ディストリビューション データベースの固定データベース ロール db_owner または replmonitor のメンバー、ディストリビューション データベースを使用しているパブリケーションのパブリケーション アクセス リスト (PAL) のユーザー、またはディストリビューション データベースの MSdistributiondbs システム テーブルに対する SELECT 権限を持つユーザーだけです。
HistoryRetention プロパティを設定できるのは、ディストリビューター側の固定サーバー ロール sysadmin のメンバーだけです。
HistoryRetention プロパティを取得すると、sp_helpdistributiondb を実行したのと同じことになります。
HistoryRetention プロパティを設定すると、sp_adddistributiondb または sp_changedistributiondb を実行したのと同じことになります。
